Do an audit of your current bulb types then do the EBay thing to buy matching types in LEDs, cheaper by many $$$ and you will get the right type, I saved $10 for each new down light.......Supercheap has some as well, stay away from van shops unless you have long arms and deep pockets.
I changed all of my T10 bulbs and over sink light to LED's. Just went on ebay and did a search by 'Jayco LED'. This lead to numerous suppliers and went by reviews to pick who I purchased from. I put 48 LED in the 2 roof lights and 24 LED in the bed lights. Lights the interior beautifully.
